Arratzua-Ubarrundia

Can you build a house on rustic land?

The Basque Country allows a new house on rustic land only when a farm needs it. Otherwise it has to go in a village, or restore a building.

Ley 2/2006, art. 28. A town plan can be stricter.

Plan in force: Plan General (a full town plan), from 2018. The region's planning viewer ↗

The national urban information system (SIU) maps the land class for 100% of the municipality.

Only the town hall can confirm it, in writing: ask for a certificado urbanístico.
